Where can you find aircraft limitations and operating restrictions?

• A. In the POH/AFM and the placards inside the cockpit.
• B. In the aircraft's maintenance logbooks.
• C. In the weather briefing provided for the flight.
• D. In the air traffic control clearances for the flight.

Answer: (A)

The official limits and operating restrictions come from the aircraft’s own documentation and visible reminders in the cockpit. The Pilot’s Operating Handbook/Airplane Flight Manual (POH/AFM) holds the authoritative limits for the specific aircraft—weight and balance, fuel and oil requirements, environmental and operating envelopes, and performance/maneuvering speed restrictions (like Va, Vne, Vno, etc.). The cockpit placards supplement this by providing quick-reference, constant reminders of critical limits you must observe during flight.

Other sources don’t define the aircraft’s limits. Maintenance logbooks record service history and airworthiness actions, not current operating limits. Weather briefings cover atmospheric conditions for flight planning, not the aircraft’s performance or safety limits. ATC clearances convey routing and altitude as directed by air traffic control, not the aircraft’s limitations.

So, the best place to find aircraft limitations and operating restrictions is the POH/AFM and the cockpit placards.
